[Tutorial] How to fix "modem is already in use" Error

(This post was last modified: 07-07-2017, 09:39 PM by X3non. )

This error is usually as a result of installing 2 or more of one manufacturer (e.g huawei, zte, etc) modem type on one PC. It would eventually result to clashing of drivers, ports and sometimes dashboard. See the procedure below for how to fix.
